Question 2a: Write an equation of the line perpendicular to line ST that goes through point R.
Julia has solved the problem but she made a mistake.
Find the error in her work and correct her mistake. Make sure to show all your work.
Julia's Work:
Corrected work:
Step 1: slope of ST ---2
Step 2: slope of the line perpendicular:
Step 3: y-y₁ m(x-x₁) R (4,-2)
y-(-2)=(x-4)
Step 4: y +2=x-2
Step 5: y + 2-2-x-2-2
Step 6: y=x-4
Step completed incorrectly:
Correct answer: y =
